Gray has written several influential books, including False Dawn: The Delusions of Global Capitalism (1998), which argues that free market globalization is an unstable Enlightenment project currently in the process of disintegration, Straw Dogs: Thoughts on Humans and Other Animals (2003), which attacks philosophical humanism, a worldview which Gray sees as originating in religions, and Black Mass: Apocalyptic Religion and the Death of Utopia (2007), a critique of utopian thinking in the modern world. Gray sees volition(意志作用、意志の力), and hence morality, as an illusion, and portrays humanity as a ravenous(貪欲な)species engaged in wiping out other forms of life. Gray writes that 'humans ... cannot destroy the Earth, but they can easily wreck(破壊する)the environment that sustains them.
